After you retrieve installation information from an INF file, there are several file-handling functions that you can use to install the files listed in an INF section. Low-level functions such as
SetupInstallFileEx install a single file.
There are also functions to handle compressed files. The
SetupGetFileCompressionInfo function returns information about compressed files. This information can then be used by
SetupDecompressOrCopyFile to copy and, if necessary, expand the file.
High-level functions such as
SetupInstallServicesFromInfSection process the installation operations in an Install or Service section. Of these,
SetupInstallFromInfSection is the most versatile because it can perform any type of installation operation listed in the Install section of an INF file. This includes the registry and INI operations listed in the AddReg, DelReg, UpdateInis, or UpdateIniField lines of an Install section.
SetupInstallServicesFromInfSection functions queue operations from an Install or Service section, respectively, to an existing file queue. Note that you must call SetupInstallFromInfSection and SetupInstallServicesFromInfSection separately to queue operations and services. For more information, see
In contrast, the
SetupInstallFromInfSection function creates and destroys its own internal queue. A common use for
SetupInstallFromInfSection is to call it after all files have been successfully copied to perform the registry and INI transactions.
On Windows 2000, DLL files may be self-registered by calling
SetupInstallFromInfSection on an INF file that includes the RegisterDlls directive in its Install section.
SetupInstallFromInfSection can also self-register 32-bit DLLs from a 64-bit process.
On 64-bit operating systems,
SetupInstallFromInfSection may be called to perform operations on the 32-bit portion of the registry. To add a registry key to the 32-bit portion of the registry, include the FLG_ADDREG_32BITKEY flag in the AddReg line of the INF. To delete a registry key only in the 32-bit portion of the registry, include the FLG_DELREG_32BITKEY key in the DelReg line. To set or clear a binary value only in the 32-bit portion of the registry, include the FLG_BITREG_32BITKEY in the BitReg line.
In addition to the functions previously listed, the Setup API includes functions that queue file installation operations, either by file, or by INF section. For more information, see
